Is there any tool to monitor the data transfer to my real time database in firebase? To see how many user connect at live time and how much data is transferred?
There's a usage tab in your Firebase Database console that has most of that information.
We also just released a tool that allows you to profile your database usage. See that tool's blog post and reference documentation.

We are a team of developers working on an app for one and a half years, with the backend using Firebase and Firestore as cloud database. We have several owners and contributors to this project. Now our Firestore data and user authentication data have been deleted and we've lost almost everything. Is there a way to see which owner/contributor has deleted our data? And most importantly is there a way to retrieve this deleted data? Thanks in advance.
Note: We are on the Blaze (paid) plan of Firebase.
You can enable audit logs for Firestore to log all operations on the database to Cloud Logging and Cloud Monitoring. That way you can see exactly what happened. You have to opt-in to this though, so this will only help you see who did what after you enable it.
Currently there is no way to find out which collaborator on the project or which Authentication user deleted the data from Firestore.
If the data got deleted accidentally from your database,as Renaud Tarnec mentioned above in comment, you can reach out to Firebase support and ask for the data to be restored.

I'm creating an android app which uses Firebase Firestore database to store data. I store about 3600 questions and about 400 images. I know that firestore support offline. But I'm not sure whether the database download itself or not every time I request data from it. And under which circumstance does the firestore database get downloaded from the cloud? Does the database get only updated when the cloud database change?
Every query performed while the app is online will download all the necessary data from the database to satisfy that query.
Any data cached locally as a result of a prior query is only used when the app is offline. As suggested by the documentation, the idea is for your app to be usable when internet connectivity is interrupted. The assumption is that the connectivity will eventually come back, and queries will revert to using the online database as the primary source of data.
I have an app which uses firebase storage and I am observing an unusual traffic to the storage. The bandwidth usage is unusually high, which shouldn't happen with the usual behavior of the app.
I need to isolate a user or a stored file which causes this unusual bandwidth usage. Is there any way I can get more information about the storage usage, other than the information shown at the Usage tab of firebase console?
Firebase Storage only tracks and shows aggregate data for the usage in your project. It does not tie this usage to specific Firebase Authentication users.
If you need that, consider adding your own tracking for this, for example by logging uploads/downloads to Google Analytics for Firebase.
You can also log to Stack Driver, although it might only be in aggregate there too. For the exact metrics, see the Google Cloud Platform documentation on its storage metrics.
Alternatively you could reach out to Firebase support for personalized help in troubleshooting. But I'm not sure if they have access to the type of data you're looking for.
I am using Firebase for almost 2 months now for my app in production and right now I am on Spark plan for sometime until I get user base. I see that the Spark pricing allows 1GB of downloads per day and 5GB of total storage but nowhere on the console I am able to see how much storage quota I have used up now. This is really important to a lot of users, if you show usage information for Database you should show it for storage as well.
As long as Storage is concerned it's actually a Google Cloud Storage Bucket, you can visit the Google Cloud Console and see the details. Firebase currently does not show the bucket usage details.
You can send them a feature request from this link :

Like Raghvendra said, you can view it on the Google Cloud Console at the following link: https://console.cloud.google.com/storage/browser/my-app.appspot.com
my-app will be your project name, and is the same as the one you use on Firebase: https://console.firebase.google.com/project/my-app/storage/my-app.appspot.com/files
After I migrated my app to console.firebase.google.com I cannot view the database usage quota, bandwidth usage and several other statistics in the firebase.com analytics tab. Is there any way to check this using new panel?
Update: you can now see your project's Realtime Database, Cloud Storage, and Hosting usage in the Firebase console.
Update (20160727): you can now see your project's database usage from the Firebase Console. Thanks for your patience!
Previous answer: the database usage quota charts are not yet available in the new Firebase Console. We're working on adding them, as well as adding similar charts for Storage and Hosting. Hang in there!
I see a new Usage tab now. Console > Database > Usage
Currently shows Sent Bytes, Storage and Connections. Looks like it may not be stable yet, because it does not match the stats reflected in my billing section.
